Rolex Cookie Monster vs Blueberry sounds simple at first. Both names point to blue Rolex watches, and both appear often in listings, dealer pages, and watch forums. That is where many readers start to get confused.
One of them changed status this year. Rolex quietly dropped the white gold Submariner from its catalog at Watches and Wonders in April 2026, so the Cookie Monster is no longer something you can order new. The Blueberry never had a catalog to be dropped from. Rolex has never admitted making it.
This guide separates the nickname from the watch. You will see what each name refers to, what the 2026 discontinuation changed, what both trade for now, and how to check a Blueberry bezel before you hand over money.
Rolex Cookie Monster: The Last White Gold Submariner
Rolex introduced the Submariner Ref. 126619LB in 2020 as part of the wider Submariner update. It replaced the Smurf (Ref. 116619LB), which collectors knew for its full blue look, and we cover the Cookie Monster vs Smurf comparison separately. This newer version kept the blue bezel but changed the dial to black.
Collectors started calling it the Cookie Monster almost immediately. The bright blue bezel framing a dark face was close enough to the Sesame Street character that the name stuck. Other nicknames circulated briefly and died. Rolex itself has never used any of them.
Case size moved from 40mm to 41mm along with the rest of the updated range. White gold makes it noticeably heavier than a steel Submariner, and you feel that the moment it lands on your wrist.
The reason it stands out is simple. It was the only Submariner in solid precious metal that did not use a matching gold bezel, and the only one pairing blue ceramic with a black dial. Since April 2026, it is also the last white gold Submariner Rolex made.

Rolex Blueberry: The GMT-Master 1675 Rolex Never Admitted To
Rolex made the GMT-Master Ref. 1675 from 1959 to 1980, built for pilots tracking two time zones. Most examples came with a red and blue bezel or a black one. Collectors use Blueberry for the rare 1675 fitted with an all-blue insert.
That bezel is the whole story, and the story is contested. Rolex USA’s position has been blunt: they never made such a watch. The insert exists, plenty of them are on wrists, and no factory record supports them.
The most repeated explanation comes from vintage dealer Eric Ku, who has described a batch of these inserts surfacing around the early 2000s after being backdoored out of an official Rolex service centre. Others argue they were special-order or military-contract pieces aimed at Middle Eastern markets.
The counter-evidence is worth knowing before you buy, and it is the kind of thing our vintage Rolex buying guide covers before you commit to any period piece. Paul Maudsley, who has worked at both Phillips and Bonhams, has said that across more than twenty years and over a hundred ref. 1675s sourced mostly from original owners, not one arrived with a blue bezel.
So the watch underneath is ordinary. The part that makes it a Blueberry is the part nobody can fully document, and that is exactly why it commands the money it does.

Cookie Monster vs. Blueberry: Most Notable Differences
Both watches share a blue theme and nothing else. One was built as a modern dive watch, the other as a vintage travel watch with a completely different job on the wrist.
Below are the five differences that matter once you look past the color.
1. Dive Bezel and GMT Bezel Do Opposite Jobs
The Cookie Monster is a dive watch. Its bezel turns one direction only and tracks elapsed time up to 60 minutes. That one-way lock matters underwater, because a knocked bezel can only ever show you less remaining time than you have, never more.
The Blueberry is a travel watch. Its bezel turns both ways and works with the GMT hand to read a second time zone on a 24-hour scale, and we walk through how to set and read a GMT step by step in a separate guide. Water resistance is 50 meters, which covers rain and hand-washing, not swimming and certainly not diving.
2. Ceramic Holds Its Color, Aluminum Fades
The Cookie Monster uses a blue Cerachrom bezel. Ceramic is harder than aluminum, shrugs off scratches, and does not fade. The numerals are filled with platinum, so the scale stays readable for the life of the watch.
The Blueberry uses an aluminum insert, which marks and fades with age. On most vintage Rolex, fading is charm. Here it is money, because the insert is the single thing that makes the watch a Blueberry at all.

3. White Gold Wears Heavy, Steel Wears Easy
The Cookie Monster’s case and bracelet are solid 18k white gold. It keeps the familiar Submariner shape but carries far more mass than steel. Some people love that dense feel. Others take it off by mid-afternoon, and the white gold vs stainless steel breakdown goes further into the trade-off.
The Blueberry is stainless steel, closer to what the GMT-Master was built to be. It is lighter, thinner through the case, and easier to forget you are wearing. On a long flight, that difference is real.
4. Caliber 3235 Runs Longer Than the Vintage Calibers
Inside the Cookie Monster is Caliber 3235, with a 70-hour power reserve, quick-set date, the Chronergy escapement, and a Parachrom hairspring. Leave it off from Friday night and it is still running Monday morning.
Most Blueberries run Caliber 1575, with earlier 1675s using the 1565. Both handle time, date, and the GMT hand. The date is not quick-set, so setting it after a stop means running the hands around the dial repeatedly.
5. Sapphire Stays Clear, Acrylic Polishes Out
The Cookie Monster has a sapphire crystal with a Cyclops. Paired with the glossy dial and Chromalight, it reads clean in almost any light and stays that way.
The Blueberry has acrylic. It picks up scratches easily, but most of them buff out with a bit of polish at home, something you cannot do with sapphire. It also gives the dial that warm, slightly domed vintage look.
What the 2026 Discontinuation Changed for the Cookie Monster
The 126619LB left the Rolex catalog at Watches and Wonders in April 2026, and there is now no white gold Submariner in production at all. Rolex retired it alongside the Pepsi GMT-Master II, leaving steel, yellow gold, and two-tone Rolesor as the only Submariner options.
Rolex offered no explanation, as usual. What it means practically is that supply is now fixed. Every Cookie Monster that will ever exist already exists, and the pool only shrinks from here as watches get worn, damaged, or locked into collections.
That has not produced a price spike. The reference was already trading below retail before the announcement, and a discontinuation does not instantly reverse that. What tends to happen is slower: fixed-supply references usually settle into steadier pricing than in-production ones, because there is no new stock to reset the floor.
For a buyer, the practical effect is on service and parts. Factory support continues for years after discontinuation, but the window is no longer open-ended, and unworn full sets get scarcer from this point rather than more common. Worth knowing how often a Rolex needs servicing before you buy one out of production.
How to Check a Blueberry Bezel Before You Buy
Since the insert carries most of the value, verification is the whole purchase. A well-preserved genuine insert can be worth more than the entire rest of the watch it sits on, which tells you everything about how motivated fakers are.
Work through these before you commit:
- Match the serial to the era. Reading the serial number tells you the case year, and Blueberry inserts are associated with mid-to-late 1970s production. A blue insert on a 1962 case is a story that needs explaining.
- Check the fade pattern against the rest of the watch. A crisp insert on a case with honest wear is a mismatch. Aluminum ages; if it has not, ask why.
- Look at the font and the pearl. Period-correct printing, spacing, and the depth of the lume pearl are where reproduction inserts usually give themselves away.
- Get it in hand or on video, under angled light. Flat catalog photos hide almost everything that matters on an aluminum insert.
- Ask what the seller believes about it. Anyone confidently telling you Rolex produced these as a catalog model is either uninformed or hoping you are.
- Price it as a watch plus an insert, separately. If the seller cannot justify the premium over a standard 1675, the premium is not real.
Nobody can hand you a factory document on this. The honest position is that you are buying a period part with a disputed origin and pricing it accordingly. The wider checklist for spotting a fake GMT-Master covers the rest of the watch.

Cookie Monster vs Blueberry Prices in 2026
The two trade on completely different logic. One is a recently discontinued modern reference with transparent comparables. The other is a vintage watch where a single component sets the price.
Cookie Monster (126619LB): Its last published US list price was around $46,600 following Rolex’s January 2026 increase. On Chrono24 the average listing sits near $39,000, with a spread of roughly $35,000 to $50,000, and around 94% of listings include box and papers. Whether that matters enough to hold out for is covered in our take on buying a Rolex without box and papers.
WatchCharts data puts the reference down about 27.8% over five years, though it was up modestly across the past twelve months. Median time to sell was around 40 days in mid-2026, which is faster than most of the market.
Blueberry (1675): A standard 1675 typically lands between $12,000 and $30,000 depending on dial, patina, and condition. Blueberries sit well above that, and the range is wide because authenticity confidence drives it more than condition does.
Auction results give the clearest anchor. A Cartier-signed Blueberry sold at Christie’s for $35,754, and stronger examples have traded higher since. Asking prices at the top end run far beyond that, but those are asks, not clearing prices, so treat them as such.
The takeaway: the Cookie Monster is easy to value because dozens of comparables are visible right now. The Blueberry is hard to value because two examples that look identical in photos can be worth $15,000 apart.

Rolex Cookie Monster vs Blueberry: Which Should You Buy?
Both carry the Rolex name and share a blue look, but they answer different questions. If you are still mapping the wider family before committing, our Submariner buying guide walks through where this reference sits. Here is how the decision usually breaks.
Choose the Cookie Monster if:
- You want a watch you can wear hard, with 300m water resistance and a ceramic bezel that will not fade
- You want Caliber 3235, a 70-hour reserve, and a quick-set date
- You like the heft of white gold and do not mind the weight
- You want a purchase you can price with confidence against visible comparables
- You are comfortable buying a reference that is no longer in production but still has factory service support
Choose the GMT Blueberry if:
- You are buying vintage Rolex history rather than daily convenience
- You want a true GMT function for tracking a second time zone
- You accept lower water resistance, an older movement, and more careful ownership
- You are willing to do real verification work on the bezel insert, or pay someone who can
- You prefer a lighter steel case and a thinner vintage profile
- You want a watch where originality and configuration matter more than specs
Where to Buy Authentic Watches Online
There are a handful of legitimate online channels for both of these. Chrono24 carries the deepest inventory of the 126619LB and lets you filter by delivery contents, which matters when box and papers move the price. We have written up what to watch for on Chrono24 before you commit.
eBay’s Authenticity Guarantee program covers watches above a set price threshold and inspects before delivery. Grailzee runs auction-format sales with shorter windows. For vintage GMTs, the major auction houses and established watch forums are where better-documented examples surface. Our guide to where to source a pre-owned luxury watch compares the channels in full.
We also buy, sell, and trade luxury watches. What clients come to us for is the conversation before the decision: tour videos of the actual watch rather than stock photos, honest condition notes including the flaws, and a real person who has handled the piece.
On a Blueberry in particular, that matters more than any listing description can.
That approach is what sits behind our 4.9-star Google rating.
If you want that kind of walkthrough on either of these, whether it is a 126619LB now that supply is fixed or a 1675 where the insert needs a proper look, we can help you source one and tell you honestly what we think of each option we find.

Rolex Cookie Monster vs Blueberry FAQs
Is the Rolex Blueberry real?
The watch is genuine, the bezel is disputed. The 1675 case, movement, and dial are ordinary Rolex production. Rolex USA has stated it never made an all-blue bezel model, and no factory documentation supports one.
The leading explanation is that the inserts left service centres as replacement parts. Genuine period inserts do exist and trade strongly, but you are buying on expert consensus, not paperwork.
Why is it called the Cookie Monster?
Collectors named it for the bright blue bezel set against the black dial, which reads like the Sesame Street character’s blue fur around a dark face. The name appeared on Instagram and watch forums within weeks of the 2020 release. A few alternatives circulated and faded. Rolex uses no nickname at all and calls it the Submariner Date in white gold.
How much is a Blueberry Rolex worth?
Far more than a standard 1675, with a range that depends almost entirely on the insert. A regular 1675 typically trades between $12,000 and $30,000, and Blueberries clear well above that.
A Cartier-signed example brought $35,754 at Christie’s. A well-preserved genuine insert alone can be worth more than the rest of the watch, while weak provenance drags the number down hard.
Which one holds value better?
The Blueberry, on current evidence, though it carries more risk. The 126619LB fell about 27.8% over five years, typical of precious-metal sports references bought at retail. Vintage GMT-Masters with scarce configurations have held up better, a pattern we break down in which Rolex models hold their value.
The trade-off: a Blueberry’s value rests on a component whose authenticity is debated, so a verification problem can erase the premium entirely.
Final Thoughts on Rolex Cookie Monster vs Blueberry
The comparison comes down to what kind of ownership you want. The Cookie Monster is a modern dive watch you can wear without thinking, now with fixed supply after its 2026 exit. The Blueberry is a vintage GMT whose value rests on one disputed aluminum insert.
Two things worth knowing before you buy. White gold is usually rhodium-plated, so high-contact spots on the bracelet can dull over years, though a jeweller can re-plate it. And on any 1675, ask for the bezel insert to be photographed off the watch. Sellers with nothing to hide will do it.
